Comet’s do not come from Earth, secondly humanity evolved from cellular microbials just the same way that a human develops in the womb and begins as a series of cells which over a nine month period of cellular growth develops or primarily evolves into a human being. How life would evolve from the the above discussed topic could be achived by introducing an new element into the environment of the microbial. A change in the microbials habitat could be a few degrees rise in temperature where seeds been grow which would attract new life in the form of bugs, birds and other species. When these species die the microbials would feed off of the carcass of the dead animal. The protein ingested and digested would then cause the microbial to split again into a new type of bacteria. As the evolution of the microbial continues due to the splitting of the cells to create new bacteria, the bacteria will begin to develop thought patterns based upon repeative actions. These actions could be as simple as the microbial traveling from it’s resting place during non-feeding times to areas where consistent foliage builds up every year. During the journey from rest to feeding and over many generations of cellular growth, the microbial would have remembered the path that it traveled to get to the food bank and then back again to it’s home by using landmarks such as pebbles that are bigger then they are but smaller for us to see. This would then equate inside of the microbials mind as taking a certain number of pulls and pushes to get to one landmark in it’s journey to and from the food storage and home. Other millions of years and a constant change in the food supply will have caused the microbial to split it’s cells billions of times which each new microbial split resulting a more intelligent and evolved bacteria that if the certain enviromental factors arre encountered then bipedal creatures then evolve just as Earthlings did.

They live hidden deep in cold, dry, dark, rock.
This is only the latest batch of this sort of life studied in Antarctica.

Another obvious, for me, implication would be greatly increased support that life exists on ice-shelled rocks orbiting planets in our solar system.

I’m not sure one can make that leap of faith. Life exists on earth (and I realize there is some debate as to how abiogenesis occurred), so a 1.5 million year old population of these organisms is hardly surprising given that bacteria are so ubiquitous on this planet. Bacteria living in this type of environment would lead me to believe that bacteria from earth could live in an ice shelled asteroid somewhere, but it provides no evidence that life could arise under such conditions, since these blood falls bacteria did not arise independent of all other life on earth.

But what’s more interesting to me is how the bacteria survived becoming almost self-sufficient. If it is possible for the bacteria to renew its energy source – why should it be impossible to us? Maybe it’s just a matter of time that we can learn from it how to cooperate with our environment.

I will add: and the other planets.

I assume that they’re fanatical about recycling carbon from dead creatures, but in every system there’s some loss. But perhaps some carbon trickles in, enough to make up for the loss, but not enough to make it an attractive to use in producing energy.
